PRIZES PRESENTED TO LAUREATES IN OSLO CEREMONY
Ceremony, Banquet Remarks Posted on Website
In September, the seven recipients of the 2008 Kavli Prizes were honored at a ceremony in Norway's Oslo Concert Hall, where His Royal Highness Crown Prince Haakon Magnus presented each laureate the Kavli Prize gold medal and scroll.
Receiving the prizes in astrophysics, nanoscience and neuroscience were: Astrophysics - Donald Lynden-Bell, University of Cambridge (UK); Maarten Schmidt, California Institute of Technology (US); Nanoscience - Louis Brus, Columbia University (US); Sumio Iijima, Meijo University (Japan); Neuroscience - Sten Grillner, Karolinska Institutet (Sweden); Thomas
Jessell, Columbia University (US); Pasko Rakic, Yale University
(US).
Joining His Royal Highness were representatives of the Norwegian
Academy of Science and Letters, the Norwegian Ministry of Research
and Higher Education, and The Kavli Foundation -- including the Kavli Prize founder, Fred Kavli -- as well as the chairs
of the Kavli Prize committees. The ceremony was also attended by guests of the Academy, Foundation and the laureates, which included noted researchers and international leaders in science. The video web cast of the ceremony and more information about the Kavli Prize laureates can be found here.

U.S. LAUREATES HONORED AT WHITE HOUSE On November 12, President George W. Bush and his Science Advisor, Dr. John Marburger
honored the first U.S. recipients of the Kavli Prize in an Oval Office
reception at the White House t his afternoon. Joining the laureates at the reception were Wegger C. Strømmen, ambassador of Norway to the United States; Fred Kavli, founder and chairman of The Kavli Foundation; and David Auston, president of The
Kavli Foundation. "Thanks to The Kavli Foundation for establishing these
prestigious awards," said Dr. John Marburger, director of the Office of Science and Technology
Policy. "We are proud that American scientists are among
the first round of recipients, and hope for more in the future. The
fields in which the awards are given are among the most exciting and
productive in science today, and the work that is being recognized has
in each case opened new opportunities for discovery by generations of
investigators. Congratulations to the recipients for their outstanding
contributions."

Astrophysics
Blowing in the Wind -- A "Weather Vane" Hope to Track the Movement of Dark Matter
In dozens of projects all over the world, researchers are trying to
detect dark matter particles by looking for evidence of those
collisions. Most of these efforts try to record the vibrations from the
"nuclear recoil" that is supposed to occur when a dark matter particle
(called a weakly interacting massive particle, or WIMP) jostles an
atom. A few others take a slightly different tact and try to map the
course of detectable particles after they are struck by WIMPs.
Researchers at MIT's Kavli Institute for Astrophysics and Space Research are involved in dark-matter searches of
both types, and one of these researchers -- Peter Fisher -- is engaged in a new project based on directional detection. With his principal collaborator, Steve Ahlen of Boston University,
they are building a detector that uses a camera in a chamber of carbon
tetraflouride gas to trace the path of electrons emitted by particle
collisions. Next stop: a mine shaft in Lead, South Dakota. Read more.

Nanoscience
The Power of Protein Machinery -- Why Understanding the "Tool Kit" of a Living Cell is One of Nanoscience's Great Frontiers
Nowhere does nature's engineering skills seem more exquisite than in the cell, where
thousands of proteins work as tiny motors to power the processes of
life. Today, researchers are eager to see if they can find new uses for this ultra-efficient machinery.
Researchers at the Kavli Institute of
Nanoscience at Delft University of Technology are among those eager to understand the nature and potential uses of this ultra-efficient machinery. With a focus on molecular biophysics -- a science that applies
mechanical concepts from physics to the study of the cell's many moving
parts -- this is described as "one of the most spectacular
frontiers in nanoscience." Read more.

Neuroscience
Understanding Our Sense of Place -- Can the Secrets of the Brain's Network of Grid Cells Explain How We Know Where We Are?
Among the vast store of memories we carry around in our heads is a large and crucial collection of maps that enable us to recognize the places we know and navigate between them.
In its research on how specialized cells interact to create the sense of place, the Kavli Institute for Systems Neuroscience at the Norwegian University of Science and Technology in Trondheim is focusing on the mechanisms of spatial computation in the normal brain. The interest in spatial computation is motivated by the possibility of achieving something Institute researchers have not seen before: the complete start-to-finish mechanics of a simple cognitive function. This may tell us how the brain works generally, as well as what goes on in Alzheimer's and other diseases. Read more.

NEWS FROM THE INSTITUTES
Study of Galaxy Clusters Detects Growth-Stifling Dark Energy
Like referees with different vantage points concurring on an important call in a tight football game, an international team of cosmologists has independently confirmed the accelerating expansion of the universe.
A decade ago, astronomers studying the relatively uniform brightness of exploding stars to estimate cosmic distances discovered that the expansion of the universe appeared to be accelerating. Gravity should have been causing the expansion, which followed the big bang, to become slower with time. This gave rise to the mystery of dark energy, the unknown force theoretically responsible for the acceleration.
Now cosmologists, including Andrey Kravtsov of the Kavli Institute for Cosmological Physics, University of Chicago, have come to the same conclusion via a completely different method: tracing the evolution of galaxy clusters. Read more.

South Pole Telescope Provides First Major Scientific Results
The first major scientific results
from the South Pole Telescope initial survey were released in early October. Four distant, massive clusters of galaxies were detected in
an
initial analysis of South Pole Telescope (SPT) survey data. Three of
these galaxy clusters were previously unknown systems and, therefore,
represent the first clusters detected in a Sunyaev-Zel'dovich (SZ)
effect survey.
The discovery was announced by John Carlstrom, director of the Kavli Institute for Cosmological Physics, University of Chicago, and principle investigator for the project. As reported in Nature, the discovery was the first step towards cataloging thousands of galaxy clusters in order to detect and understand dark energy.

Light Triggers a New Code for Brain Cells
According to a study published in Nature, brain cells can adopt a new chemical code in response to cues from the
outside world. The discovery opens the possibility that brain chemistry could be
selectively altered by stimulating specific circuits to remedy low
levels of neural chemicals that underlie some human ailments.
The findings of Davide
Dulcis, a University of California, San Diego postdoctoral fellow, and Nicholas Spitzer, co-director of UCSD's Kavli Institute for Brain and Memory, was Nature's cover story in the Nov. 13 issue. Read press story and hear Nature's Neuropodcast.

Brain's Navigation System Relies on Broad Spatial Scale Researchers at the Kavli Institute for Systems Neuroscience in Trondheim have uncovered new details on the behavior of grid cells, which the brain uses to form a metric map of the environment -- key for our ability to navigate spaces and landscapes.
In Science, researchers announced that, contrary to previous thinking, the brain's metric map operates on a wide range of spatial scales. Using rats, they recorded the activity from place cells in the hippocampus, which work collectively to signal the animal's current location with great accuracy. They found that "short-range" place cells are located in the upper part of the hippocampus, with longer-range place cells increasing as one progresses deeper into this area of the brain. For rats, the scale begins at approximately 30 cm to about 10 m. Among the findings: there is a limit to the size of the area to which a place cell will respond.
There is also a rhythm to how groups of neurons work together to form maps and encode information. In Nature, researchers showed that a temporal code, also known as phase precession, is found in some parts of the entorhinal cortex, and that the code is very similar to the hippocampal temporal code. These findings bring us closer to understanding the biological mechanisms that can generate the precise spike timing during behavior and facilitate sequence learning via synaptic plasticity.
